Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a cooling device for screen printing products. Background Art

[0002] Screen printing refers to using a screen as the printing plate base and making a screen printing plate with patterns and texts through a photosensitive plate-making method. Screen printing consists of five elements: a screen printing plate, a squeegee, ink, a printing table, and a substrate. The basic principle of screen printing is that the ink can pass through the mesh holes of the graphic part of the screen printing plate, while the ink cannot pass through the mesh holes of the non-graphic part. During printing, ink is poured at one end of the screen printing plate, and a certain pressure is applied to the ink part on the screen printing plate with a squeegee, while moving uniformly towards the other end of the screen printing plate. The ink is squeezed from the mesh holes of the graphic part onto the substrate during the movement.

[0003] After screen printing on the surface of an article, the printing ink often cannot dry and solidify quickly. During the cooling and drying process of the printing ink, it is also not allowed to come into contact with it, otherwise the printed pattern will be messed up, which has an adverse effect on the efficiency of storing and stacking screen printing products.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of clear description and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0021] Refer to Figures 1 - 4, A cooling device for screen-printed products, including a base 24. In the center of the upper end face of the base 24, a printing frame 10 is fixedly installed. On the upper end face of the base 24, a driving shaft 1 is rotatably installed. On the circular surface of the driving shaft 1, a belt roller is fixedly installed. On the circular surface of the belt roller, a conveyor belt 11 is rotatably sleeved. The other end inside of the conveyor belt 11 is rotatably connected to the belt roller, and a secondary rotating shaft 19 is fixedly installed inside the belt roller. The secondary rotating shaft 19 is rotatably installed on the upper end face of the base 24.

[0022] At the end face of the driving shaft 2, a driving bevel gear 2 is fixedly installed. The driving bevel gear 2 is meshed and linked with a driven bevel gear 3. At the end face of the driven bevel gear 3, a reciprocating lead screw 4 is fixedly installed. The other end of the reciprocating lead screw 4 is rotatably installed on a fixed plate 8. On one side of the fixed plate 8, a limiting rod 7 is fixedly installed at the same time. On the circular surface of the limiting rod 7, a limiting sleeve 6 is slidably connected. On the circular surface of the limiting sleeve 6, a sliding sleeve 5 is fixedly installed. The sliding sleeve 5 is threadedly connected to the reciprocating lead screw 4. On the circular surface of the sliding sleeve 5, a rack 9 is fixedly installed. The rack 9 is meshed and connected with a gear roller 12. The gear roller 12 is rotatably installed on the upper end face of the base 24.

[0023] The gear roller 12 is also meshed and connected with a driven rack. On the plane of the driven rack, a piston 13 is fixedly installed. The piston 13 is slidably sleeved with an air jet cylinder 14 on the periphery. The air jet cylinder 14 is arranged above the conveyor belt 11. The air jet cylinder 14 is fixedly installed on the upper end face of the base 24. At the bottom end of the circular surface of the air jet cylinder 14, three through air jet openings 23 are opened. At the end face of the air jet cylinder 14, a through circular opening is opened. Inside the circular opening, a limiting plug 15 is arranged. The limiting plug 15 includes two circular plates. Between the two circular plates, a cylinder is fixedly installed. The diameter of the cylinder is smaller than the diameter of the through opening. Between the circular plate outside the air jet cylinder 14 and the end face of the air jet cylinder 14, a top spring 16 is fixedly connected.

[0024] On one side of the printing frame 10, an L-shaped fixing strip 17 is fixedly installed. On the side of the fixing strip 17 close to the conveyor belt 11, a blowing plate 14 with a cross-shaped cross-section is rotatably installed. At the end face of the blowing plate 14, a conduction cylinder is fixedly installed. On the circular surface of the conduction cylinder, a second belt roller is fixedly installed. On the circular surface of the second belt roller, a conduction belt 20 is rotatably sleeved. The other end of the conduction belt 20 is rotatably sleeved with the secondary rotating shaft 19 through the second belt roller. Through the blowing plate 14, the air flow above the conveyor belt 11 can be accelerated, which is more conducive to the cooling effect of the printed product.

[0025] At the edge of the upper end face of the base 24, an inclined guide plate 21 is fixedly installed. On both sides of the inclined surface of the guide plate 21, baffles are symmetrically fixedly installed. When the printed product is printed on the conveyor belt 11, it continues to move with the conveyor belt 11 and slides into the air box 25 through the guide plate 21. The baffles on both sides of the guide plate 21 can keep the printed product in a stable state during the sliding process and keep it neat after falling into the air box 25.

[0026] Two receiving plates 22 are symmetrically fixedly installed on one side of the base 24 close to the guide plate 21, and a bellows 25 is placed on the upper end surface of the receiving plate 22. The bellows 25 is fixedly connected by two layers of box bodies, and is divided into an inner box body and an outer box body. A plurality of through second openings are provided on the four inner walls of the inner box body, and a rectangular opening is provided on the lower end surface of the outer box body. When in use, the second openings provided on the inner box body of the bellows 25 are conducive to the ventilation of the printed matter and prevent heat accumulation. If you want to further increase the cooling effect, you can place a fan or other blowing equipment under the bellows 25. This can accelerate the air flow, so that the flowing air passes through the rectangular openings and the second openings and blows toward the printed matter, which is more conducive to cooling.

[0027] Four support columns are rotatably mounted at the four corners of the lower end surface of the base 24, and a rotating wheel is rotatably mounted on the lower end surface of each support column.

[0028] Compared with the prior art, the beneficial effect of the utility model is that the torque generated by the driving shaft of the conveyor belt drives the rotation of the reciprocating screw, and then drives the rotation of the blowing plate and the jet movement of the piston, so that the air flow rate on the surface of the printed matter is increased, thereby cooling the screen printed matter.

[0029] In the utility model, when in use, the driving shaft 1 rotates, the driving shaft 1 drives the active bevel gear 2 to rotate, the active bevel gear 2 drives the driven bevel gear 3 to rotate, the driven bevel gear 3 drives the reciprocating screw 4 to rotate, the rotation of the reciprocating screw 4 drives the sliding sleeve 5 to reciprocate on the reciprocating screw 4, and at the same time the sliding sleeve 5 drives the rack 9 to reciprocate, the reciprocating motion of the rack 9 drives the gear roller 12 to continuously rotate with a changing direction, the rotation of the gear roller 12 drives the driven rack to perform a linear motion, and the driven rack drives the piston 13 to continuously slide inside the jet cylinder 14, so that the air inside the jet cylinder 14 is continuously compressed and then inhaled, and then the air is ejected from the jet port 23.

[0030] In the process of the piston 13 driving the jet tube 14 to spray paint, when the piston 13 moves toward the limiting plug 15, the air inside the jet tube 14 is compressed, and the disc inside the jet tube 14 will press against the circular opening under the action of air pressure and the elastic force of the top spring 16, so that the compressed air is ejected from the jet port 23. When the piston 13 is away from the circular opening, negative pressure is generated, and the limiting plug 15 moves toward the inside of the jet tube 14 under the action of air pressure, allowing external air to enter the inside of the jet tube 14, and the printed matter is cooled by jetting repeatedly.

[0031] The secondary rotating shaft 19 rotates under the driving action of the driving shaft 1 and the conveyor belt 11. The secondary rotating shaft 19 drives the conduction cylinder to rotate through the conduction belt 20, and the conduction cylinder then drives the blowing plate 14 to rotate, accelerating the air flow above the conveyor belt 11. When the printed matter is printed and moves to the end along the conveyor belt 11, it will continue to slide along the guide plate 21 and finally fall into the air box 25.

[0032] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0033] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
